  DOS Protected Mode  -  User's Guide pp 10-11
  -------------------
  DPMI (DOS Protected Mode Interface) allows use of compiler in protected
  mode, giving access to all computer's memory. Protected Mode Interface is
  transparent to user.

  By default DPMI allocates all available extended and expanded memory.
  In Autoexec.bat SET DPMIMEM = MAXMEM 2000 (Kbytes) to make only 2MB
  available.

  See also Language Guide Ch17 pp 193-213 for Programming in the DOS
  Protected Mode, using up to 16 Mbytes of memory.


  Indexed pointers to array   -  Language Guide p 55
  --------------------------
  A pointer to an array can be indexed  eg.  Results.Data^[J]

  See also demonstration program ARRPTR.PAS -> .EXE by R Shaw.


  Dynamic Methods    -  Language Guide pp 283-5
  ----------------
  A dynamic method table (DMT) encodes only the methods that were overridden
  in the object type. When descendant types override only a few of a large
  number of inherited late-bound methods, the dynamic method table format
  uses less space than the format used by VMTs.


  Turbo Vision Events   -  Turbo Vision Programming Guide  p 156
  --------------------

  Define new categories of events by using the high-order bits in the What
  field of the Event record. By default, Turbo vision will route all such
  events as broadcast events.
  See page 152 for the Event.What field bit mapping.

  Turbo Vision Hierarchy  -  Turbo Vision Programming Guide  pp 94-4
  ----------------------
  New Validate unit.


  Inheritance  -  Turbo Vision Programming Guide  pp 98
  ------------
  Fields and methods inheritance table with overridden methods shown with
  line through.


  Using Bitmapped Fields   -  Turbo Vision Programming Guide  pp 109
  -----------------------
  Individual bits or flags set (=1) or cleared (=0)
  Set by OR operator
       eg. MyButton.Options := MyButton.Options OR ofPostProcess;

  Cleared by AND NOT    eg.  field := field AND NOT flag;

  Toggled by XOR        eg.  field := field XOR flag;

  Checked by AND        eg.  if field AND flag = flag then

  Check mask            eg.  if flag AND MASK <> 0 then


  Object Windows   -   Object Windows Programming Guide
  ---------------
  User should read other books on Windows Application Programming Interface
  (API).  page 1

  Need to know Pascal, Windows and OOP. Also pointers and dynamic variables.
  page 3.

  Use the units OWindows, ODialogs, OPrinter and Objects (for collections
  and streams), plus WinTypes and WinProcs. Also OMemory.  p 95.

  Object hierarchy  pp 92-3.
